Not really: in Word you don't have to unlock an image to
move it or resize it again.

Although I understand the current behavior, it is really awkward
and drives my students nuts.  Every time they want to move or
resize an image they first have to unlock it, and then remember to
lock it when they're done.  These are 8th graders; the easier the
interface the better.

The current behavior makes one of my beginning assignments, a
flip-card animation, really tedious to do.  (I'm reluctant to
give up the assignment, as it's how I introduce loops.)

Now if there were a control key that you could hold down that would
override the lock as you click and drag on an object or its handles,
that would solve the problem.  (RR, are you listening???)
